基于用户协同过滤的程序代码，参考《协同过滤推荐算法研究》-User-based collaborative filtering program code, refer to " collaborative filtering recommendation algorithm"

使用MapReduce实现的给予项目的协同过滤算法，只实现了构建用户向量和协同矩阵，仅供参考-Give the project implemented using MapReduce collaborative filtering algorithm, only to realize the construction of the user vector and collaboration matrix, for reference
